Edge Blend procedure
1. Align the projectors as they will be used in the array.
Each projector should be perpendicular to the
screen, or as close as possible. Ideally, each
projector should allow for a minimum of 20% screen
overlap where it is adjoined by other projectors.
Overlaps should be the same in size across the
array.
How to align the projectors:
• Ideally, all alignment should be achieved by
physically moving the projectors and by using
the Lens Shift and Zoom functions.
• If necessary, use Image > V Position and
H Position.
• Do not use geometry corrections.
Example: 1080p projector overlapped on all
sides
1
Overlap to the left
This overlap takes 20% of the image width, or
384 px.
2
Overlap to the top
This overlap takes 20% of the image height, or
216 px.
3
Area without overlaps
This area is also called unblended region.
